SPECIFICATION forming'part of VLetters Patent No. 287,177, dated October23, 1883.

' Application and Apmscrisss. m0 modem 10 all L11/"tom, it may concern:

Be it known that I, WILLARD W. SAWYER, of Springfield, in the county ofHampden and State of Massachusetts, have invented a new and usefulImprovement in Hand-Stamps, of which the following is a speciiicationand description.

My invention relates more particularly to that class of hand-stampswhich are designed for dating purposes, and in which movable rubberbands having raised printed characters made thereon are moved around andupon a supporting block or frame, to bring any desiredprinting-character into position beneath said frame to make an imprint;and the object of the invention is to provide a hand-stamp in which therubber printing-bands are properly and efficiently supported, and arepositively actuated without undue strain upon any one portion of theprinting-bands or of the printing-characters, and to cause thecharacters't-o move promptly and easily into position to make theimprint; andIaccomplish this by the mechanism substantially ashereinafterdescribed, and illustrated in the accompanying drawings, inwhichf Figure I is a side view of a hand dating-stamp made according tomy invention. Fig. II is an end view ofthe same. Fig. III is areverseside view ot' the same. Fig. IV is a vertical section of the same atline A of Fig. III. Fig. V is a plan view of the lower face of the stampwith the die-'plate removed. Fig. VI is aside view of the frame whichcarries or supportsv the rubber printing-bands, with the latter in placethereon and the frame removed from its position in the stamp-case. Fig.VII is avertical section ofthe same at line B of Fig. VI, showing one ofthe side actuating-wheels as engaged with its printing-band. Fig. VIIIisa vertical section at line C of Fig.VI, Showing the other side operatingor actuating wheel as engaged with its printing-band. Fig. IX is a planview of the stamp-case, and Fig. X is a horizontal transverse section atline E of Fig. VI. y

In the drawings, 2 represents the stampcase, made of rectangular shape,in each end of which, inside, I make a vertical groove, 23, and whoseupper end is provided with a cylindrical shank, 27 having an externalsereW-r composition-and the middle portion, '5, of the frame is madelonger than the end portions, 6,

according as the printing-band used thereon is longer than the bandsused on the end portions, as shown clearly in Fig. VI; and Imake acavity, 25, in the middle. portion of this frame, as shown clearly inFig. IV, and place a rubber band, 41, having raised numerals orcharacters, as 12, made thereon, equaling in number and representing thedays of the month. I then place a toothed wheel, 7, to revolve on itsaxis in the frame at 9, the teeth 8 of said wheel being of suchdistances apart as to enter the spaces between the raised figures orcharacters on the printing-band, as shown clearly in Fig. IV, and whenthe said wheel is turned on its axis its teeth 8 actuate or-move therubber band 41 around the frame, the raised characters 12 on the bandserving the purpose of teeth, With which the teeth of the Wheel engageto move the band. The frame 6, on each side of its middleportion, 5, hasalso a cavity, 26, madein each said portion, on the opposite side oftheframe from that containing the cavity 25, and around one of theseportions Iplace a shorter rubber printing-band having raised charactersmade thereon corresponding with and representing the months in the year,and around the other end portion, '6, I place a similar rubberprintingband, 41, having raised printing-characters made thereonrepresenting any desired series of years, and also any other charactersdesired, as shownv clearly in Fig. VI. In front of each cavity 26, ineachend portion, 6, ofthe frame, at 14, I place a similar toothed wheel,7 to revoIve on its axis, whose teeth 8,when therubber printing-bandsare in place, enter the spaces between the raised characters 12 on thesaid bands, so that when the wheel in front of the month-band is turnedits teeth actuate or move the month-band, and the toothed wheel in frontof the. year-band also actuates that in the same way. The wheels 7 wouldbe opera- IOO and is secured by a screw, 18,turned in through fwardly-proj ecting lug, 17.

tive to actuate the printing-bands if the cavi- .ties 25 and 26 were notmade in the frame;

but I prefer to make the cavities, in order to give the band a longerbearing-surface on its wheel, and thereby cause a greater number of theteeth of each wheel to engage with the raised printing-characters of itsband. This frame 6 may be cast or made solid or in one piece, and I makea straight flange, as 22, on each end of the frame, which proj ectsoutward a little distance therefrom, and with thebands and wheels all inplace I insert the frame into the case 2 from its lower open face, theflanges 22 passing up into the grooves 23,"made inthe ends of the ease,inside, as shown clearly in Fig. V, the middle part, 5, with its rubberprinting-band thereon, projecting up through the hole 28, made in theupper end of the-shank, as shown in Figs. IV and IX. Vhen inserted upinto place in the case, the frame is secured by a screw, 19, turnedthrough a hole, or a vertical slot, 20, made through the case-I prethelatter-and into Va threaded hole in the frame. A die-plate, 15, havingan elongated opening through it, is placed up against the lower end ofthe case, with one or more overhanging lugs, 32, forced againstcorresponding lugs, 33, made in the lower end ofthe case,

the lower part of the case and against an up- I make the lower end, 10,of the frame 6 fiat, so that the printing-characters of all the bands,when in position tovmake an imprint, are in a line below this flat lowerend of the frame, and when the die 16 is fixed to the plate 15 theframe, with all its bands in place, may be raised or lowered in the caseby loosening the screws 19 in the slots in the ends of the case andmoving the frame either up or down until the. printingfaces of thecharacters on the bands are in the,

same plane with theprinting-faces ofthe characters on the die 16, andthe screws 19 are then tightened.

When the frame 6, with all the printing rubber bands thereon, is securedin place in the case, the middle toothed wheel, 7, which actuates `theday printing band, projects slightly or .is exposed through the opening4, as shown in Fig. III, and by pressing against the teeth" of saidwheelthrough said opening the wheel is revolved to bring the desiredprinting-character beneath the iiat end of the frame 6, to make theimprint. The other two wheels 7, which aetuate or move the month andyear printing bands, project or are exposed through the openings 3 inthe opposite side of the case, as shown in Fig. I; and these wheels maybe turned by pressing against the teeth to move their bands and bringthe desired printing-characters into position to make an imprint.

The hand-piece 24 may be bored out, so that the long part 5 of the frame6 may project up through the top of the case and into the hand-piecewhen the latter is screwed to the shank.

It will be seen that by making thecavities 25 and 26 in the frame I amenabled to give a long bearing of the rubber printing-bands against theactuating-wheels 7, and cause sev.- eral ofthe teeth of each wheel toengage against the raised portions of the band and between the printingcharacters at the same time, which feature obviates any undue strainupon any one part of the printing-band, and yet causes the band to moveto its position promptly and quickly.

It is evident that ahand-stamp whose frame 6 is made to carry only asingle rubber printing-band having thereon raised printing-charactersother than dating mattermay be used and the band be moved by its wheelin the same manner without departing from the invention in the least.

Of courseeach toothed actuating-wheel 7 might be pivoted in the case 2,but` in the same relative position with its printing-band,

`when the frame is in place in the case; but I prefer to pivot the saidwheels or place them on their axes in the frame, as hereinbeforedescribed.

By casting the stamp-case solid I am enabled to make it compact, andintroduce the frame, bands, and actuating wheels at the lower open face,and construct the stamp very cheaply and with less liability of derangement of parts than when the case is made in separate portions andsecured together.

Having thus described my invention, what I claim as new isy j 1. In ahand-stamp, the combination of a frame, one or more rubber bands havingraised printing-characters thereon and placed around said frame, and atoothed wheel adapted to be moved on its axis in front of each saidband, and whose teeth engage with said raised portions of the band andbetween the printingcharacters, to actuate or move said band and bringany one of said characters thereon into position to make an imprint,substantially as` wVILLARD VV. SAVYER.
